Several Factors Affecting The Sound Quality Of Video Conference Omnidirectional Microphone

Several factors affecting the sound quality of video conference omnidirectional microphone

Video conference omnidirectional microphone is an audio product that has been gradually recognized by video conferencing in recent years. It integrates a microphone and a speaker, and has echo cancellation, noise filtering, and comprehensive sound collection. The function is so unanimously recognized by the majority of users.

However, some users also report that the sound quality is not good, there are echoes, there are noises, then we will analyze several factors that cause these problems.

First: how the performance of the video conference omnidirectional microphone itself

The video conference omnidirectional microphone itself should have the echo cancellation function, how the sound quality is restored, whether there is noise, and how effective the pickup distance is. These factors directly determine the sound quality of omnidirectional microphones in remote video conferencing. Sound quality, how do we listen to the reduction by recording the song,

this makes it very intuitive to feel the sound quality, we can simultaneously record while playing music to detect the echo processing of the video conference omnidirectional microphone. Through these tests, you can roughly determine whether the performance of the video conferencing omnidirectional microphone is superior.

Second: the operating system used to handle the sound quality twice

We usually see two computer operating systems, XP, WIN7. These two systems have different processing of audio. Let's talk about XP system first, under XP system, we should make those settings, put the mouse in the lower right corner of the computer desktop, click the volume icon right-click property - voice - sound output - advanced - adjust the audio acceleration and sample to the left. The purpose of this is to prohibit the secondary amplification of the audio by the XP system to ensure the maximum performance of the original video conference omnidirectional microphone. We can't do much under the WIN7 system, but we can adjust this by lowering the microphone pickup volume and the speaker volume.

Third: video conferencing software secondary processing of sound

Under normal circumstances, the video conference will encode and decode the audio, with high sound quality, low quality, and will also eliminate echo, eliminate noise and other similar options. At this time, we choose according to the network conditions, remove the echo cancellation, eliminate the noise, the purpose is also Disable the processing of audio by video conferencing software, and maximize the performance of omnidirectional microphones for video conferencing
